Hi everyone,
I just found out that in R2012a, there is a new file format called SLX for saving simulink model. SLX is a binary file.
The old file format is MDL which is a text file.
I prefer the MDL file and actually in my work I need the plain text MDL file.
Does this mean in the future, Simulink will not open MDL file?
Thanks Kevin

The SLX format for Simulink is actually a Zip file which contains in it a collection of XML files and images in at least PNG format. It is possible to work with SLX files with standard tools, it's just a little more involved than MDL files. One reason for the change is that MDL files are plain text files that can be saved in different character encodings. If any non ASCII characters such as vowels with accent marks is present, it can be corrupted if the wrong encoding is used. XML files do not suffer from this issue and will always be read correctly by an XML parser. They look like text files, but have a very well-defined format.

SLX is a compressed file that contains model information in XML format.
There is information about the format. http://www.mathworks.com/help/simulink/ug/saving-a-model.html#btbr7kx-1
If you want to dig into it, you can open the file in say winzip and extract it. I just renamed the file to filename.zip and extracted it and you can see the model in XML format.
However to answer your future question, we'll never know, as of now Simulink very much supports MDL, and several shipped models are in MDL
